摘要

摘要: 根据粤西海域漂流瓶的运动轨迹、海流周日定点连续观测结果、温盐大面站调查的资料、船测ADCP的流矢量和卫星遥感SST的综合分析结果发现,夏季珠江口以西的近岸流大部分时间向西运动,它构成琼州海峡东部气旋涡的北翼;向西的沿岸流还有一部分海水通过琼州海峡向西进入北部湾.并不像传统观点认为的那样,琼州海峡冬季余流向西,夏季余流向东.如果西南风强盛,向西的沿岸流方向可以暂时转而向东北.还揭示了粤西海域、琼州海峡和北部湾北部海域夏季沿岸流的重要特征并进行了机制分析.

Abstract: Based on data of tracts of drifting bottles, current at continuous stations, temperature and salinity in some cruise investigations, ADCP (current) and AVHRR(SST) in the west coast of Guangdong Province, the synthetic analysis results show that the coastal currents in the west of the mouth of Zhujiang River flow mainly westward in summer, composing the north branch of cyclonic gyre in the east of Qiongzhou Strait, and partially water flows westward into the Beibu Gulf through the Qiongzhou Strait.The coastal current pattern is no tidentical with the traditional current system, which is that the residual current flows westward in the Qiongzhou Strait in winter and eastward in summer.The coastal current, which is westward, maybe temporarily turn to northeast only if the southwestern wind is strong.The important characteristics of coastal current in the west coast of Guangdong Province, in the Qiongzhou Strait and in the north of Beibuwan Gulf are analyzed and their mechanism are explained.
